To extract an object, you use tools in the Extract
dialog box. First you draw a highlight that marks
the edges of the object, and define the object's
interior. Then you can preview the extraction and
redo it or touch up the result as needed. When you
extract the object, Photoshop erases its
background to transparency. Pixels on the edge of
the object lose their color components derived
from the background, so they can blend with a
new background without producing a color halo.
You can add back opacity to the background
and create other effects by using the Edit > Fade
command after an extraction.
For more information, see "Blending filter
effects (Photoshop)" in online Help.
To extract an object from its background:
1
In the Layers palette, select the layer containing
the object you want to extract. If you select a
background layer, it becomes a normal layer after
the extraction.
To avoid losing the original image information,
duplicate the layer or make a snapshot of the
original image state.
Note: If the layer contains a selection, the extraction
erases the background only in the selected area.
Choose Image > Extract.
2
You use tools in the Extract dialog box to specify
which part of the image to extract. You can resize
the dialog box by dragging its lower right corner.
3
Specify options for tools in the dialog box
(you can change these settings at any time):
•
For Brush Size, enter a value, or drag the slider to
specify the width of the edge highlighter, eraser,
cleanup, and edge touchup tools.
•
For Highlight, choose a preset color option,
or choose Other to specify a custom color for
the highlight.
•
For Fill, choose a preset color option, or choose
Other to specify a custom color for the area
covered by the fill tool.
•
If you are highlighting a well-defined edge, select
Smart Highlighting. This option helps you keep
the highlight on the edge, and applies a highlight
that is just wide enough to cover the edge,
regardless of the current brush size. Smart
Highlighting can greatly improve the extraction
when the object and background have similar
colors or have textures.
Adjust the view as needed:
